Abstract: 657,490. Electric coils. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 10, 1947, No. 27280. Convention date, Oct. 12, 1946. [Class 35] [Also in Group XL (a)] An electromagnetic device for deflecting the beam in a cathode-ray tube in two directions over the fluorescent screen comprises a core, Fig. 2, of steel wire or ribbon wound into a coil 5 and surrounded by a non-magnetic, preferably copper sleeve 6, and a plurality of coils 15, wound longitudinally on the composite core to the same depth, alternate and intermediate coils being respectively connected to form the two deflecting circuits. Insulators 9, 10, 11, 12 of cellulose acetate space the coils from the core and C-shaped guides 14, also of cellulose acetate separate adjacent coils from one another; the guides 14 fit in notches at the ends of members 9, 10. The wire of the core has its longer crosssectional dimension perpendicular to the longitudinal axis of the coil into which it is' wound, and is of high permeability material. The non- magnetic sleeve 6 serves to increase the reluctance of the flux path external to the wound coil of the core, and may have flared ends as shown to hold the coil in position. In winding the coils, those of the vertical deflecting winding are wound first ; an insulator 40 is then wrapped round the assembly and the horizontal deflecting coils are wound on. The Specification as open to inspection under Sect. 91 refers to differing numbers of turns in the different coils. This subject-matter does not appear in the Specification as accepted.

Title: A process for separating yttrium from rare earth mixtures containing the same
IPC: C01F17/224
Filed: 1958-08-28
Abstract: Yttrium is separated from an aqueous solution containing rare earth metals by precipitating said metals as double potassium and/or ammonium chromates from a solution containing at least 0.02 moles/l. bichromate and recovering yttrium from the remaining solution, e.g. by precipitation as carbonate, the latter solution containing at least 15 g./l. of yttrium and rare earth metals calculated as oxide. The precipitation may be performed with aqueous ammonium or potassium hydroxides, carbonates or chromates or with pure or diluted gaseous ammonia or may be performed in the presence of at least 0.2 moles/l. of potassium and/or ammonium ions and initially not more than 1 mole/l. of nitrate ions by means of sodium hydroxide, carbonate, bicarbonate or chromate. Potassium and/or ammonium chloride may be added to the original solution; nitrates should not be present in greater concentration than 3 moles/l.  To avoid formation of basic salts, the initial solution preferably has a concentration of 100-200 g./l. rare earth oxides; the preferred precipitation temperature is 45-85 DEG C. The precipitation is preferably carried out in several stages. The fractions thus obtained may be separately refractionated after dissolving in the minimum quantity of hydrochloric acid or after dissolving may be mixed with a solution of the original material: if the original material contains less than 60% of yttrium oxide, the solution remaining after fewer precipitations may be further treated in the same way after mixing with a solution of material of similar composition to that of the final solution or using it to dissolve such material, or the yttrium content may be enriched by adding richer precipitated fractions.

Reinforced, laminated belting is made by assembling reinforcing sheets interlayered with thermoplastic material in sheet or paste form between protective, heat-conducting sheets, passing the assembly first to a heating zone to fuse the thermoplastic material and later to a cooling zone where it is cooled under pressure, and stripping off the protective sheets after removing the belting from the cooling zone. As shown, the belt layers e are carried, while assembled between endless metal bands c and d, between a pair of press platens each divided into a heated section a, a<SP>1</SP> and a cold section b, bl. At the end of each pressing cycle, the endless metal bands are moved a sufficient distance to bring the hot-pressed portion of belting into the cold section of the press. The belts may be moved directly or by applying traction to the finished belting. In alternative forms (a) two presses may be used in series, one with hot, one with cold, platens; in this case, the cold press may be used as a clamp enabling the unpressed portion of the belt to be stretched before hot - pressing; (b) the lower platen may be replaced by two independently-operated, separate platens, permitting stretching as in (a), (c) the endless metal bands may be replaced by metal or thin rubber hydrochloride webs uncoiled at the entry end of the press and wound up at the exit and, (d) one or both endless bands may have both horizontal flights running between the platen and the laminated belt, (e) instead of a cold platen press, the laminated belt may be pressed against a cold roller by an external band. The heating may be effected without pressure, by radiation, contact, or highfrequency induction. Specification 733,623, [Group V], is referred to.

Abstract: 248,062. Backhouse, H. T. Nov. 25, 1924. Dropping-roller and like sheet feeds; sheetregistering devices.-In a sheet-feed apparatus comprising two or more front stops and sheet-forwarding means operable in conjunction with the stops, means are provided which normally prevent the stops lifting and the sheet-forwarding means operating, but which are tripped when a sheet is registered against all of the stops. Each stop 5 is carried by a shaft 9 which is rocked in synchronism with a drop-roller 6 by a pin-and-slot connection 13, 14, the driving-gear consisting of a cam 24, a spring-controlled bell-crank lever 21, a link 20, and a crank 19. Spring contacts 25, 26 are provided on the stop 5 and feed table 16, and when no sheet is fed these serve to energize an electromagnet 34 which lifts a stop 30 on a bellcrank lever 32 into engagement with an arm 31 on the shaft 10 and thus prevent actuation of the stop 5 or drop-roller 6. A pair of contacts 25, 26 are provided at each stop 5 and are included in parallel in the energizing circuit of the magnet 34, so that, unless the fed sheet engages all the stops 5 and breaks all the contacts, the stop 30 continues in operation. In a mechanically-operated device shown in Fig. 2, a pawl 35 carried on each stop 5 engages a recess in a sheet guide 38 and prevents movement of the stops and droproller if a sheet is absent or not properly registered. In a third form shown in Fig. 4, a projection 41 on the drop-roller arm 8 normally engages a stop 40 on a pendant arm 39 on each stop 5 and prevents actuation of the stops and drop-roller, but when a sheet is fed the sheet engages the arms 39 so as to allow the stop 40 to move out of the path of the projection 41. Specification 217,283 is referred to.

Abstract: 1,255,296. Radio signalling; substation circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 11 June, 1970 [16 June, 1969], No. 28278/70. Headings H4K and H4L. In a cordless telephone comprising radio units in the handset and in the instrument body on which the handset rests when not in use, speech signals being conveyed from the handset to the body and from the body to the handset on first and second carrier frequencies respectively, the body includes a threshold circuit which detects when the received first carrier falls below a predetermined level and causes a special signal to be transmitted by the second carrier frequency to the handset to indicate to the user that the handset is too far from the instrument body. Such detection by the threshold circuit may operate a trigger circuit to disconnect the speech signals received from the handset from a hybrid in the body so that the resulting lack of sidetone in the handset receiver forms the special signal. Alternatively the trigger circuit may disconnect the speech signals received from the subscriber's line from the radio transmitter in the body, the resulting lack of speech signals in the handset receiver forming the special signal. In a further arrangement the trigger switches on a tone generator and connects it to the radio transmitter in the instrument body.
